[Freeswitch-users] Audio Playback Issue

Hi everybody, I'm trying to reproduce some wav audio files in a one leg call. The call is originated programmatically by a C module written by myself. The issue is when the destination is a SIP or GSM, the audio is reproduced OK, but when the destination is land line, the audio is chunked and cutted. I already tried many sorts of sample rate - always on wav format - but I always had the same result. I really had understood that the issue is related with the type of destination line, but I'm accepting any suggestion to solve this.
